3 Things you will need if you plan on getting into coin collecting:
A 10x Magnifying Loop
A pair of white cloth gloves (cotton)
A good eye for detail
Hold the coins on the edges - don’t touch the flat surfaces (the obverse and the reverse - the two sides)
Storage:
Safety-deposit box
Safe in your home
Think about getting insurance (you will need to get them appraised)
The Sheldon Grading Scale 1-70 (70 is perfection - no marks at all)
(Mint-state coins have never been touched by human hands. Circulated coins have, as they have been in circulation.)
